        <header><h3>Abstract</h3></header>

    <p>During  the  ontology  conceptualization  activity,  developers usually generate preliminary models of the ontology in the form of diagrams. 
      Such models drive the ontology implementation activity, where the models are encoded using an implementation language, typically by means of ontology editors.</p>
    
    <p>The goal of this demo is to take advantage of the developed ontology conceptualizations in order to accelerate the ontology  implementation  activity.</p>
    
    <p>For  doing  so  we  present  Chowlk,  a converter to transform digital UML-based ontology diagrams 
    into OWL. This system aims at supporting users in the generation of the first versions of ontologies by reusing the ontology conceptualization output.</p>

    <header><h3>Main Features</h3></header>

    <p>Chowlk is a web application that takes as input an ontology conceptualization
      created with diagrams.net and generates the OWL implementation.</p>

    <header><h3>Conclusions and future work</h3></header>

    <ol>
      <li>The Chowlk converter that facilitates the ontology development process by leveraging the ontology conceptualization diagrams to transform them into OWL</li>
      <li>Next steps involve the announcement and promotion of the system to get feedback from users</li>
      <li>Development of a plugin for diagrams.net in order to embed the ontology generation feature into the diagramming tool</li>
    </ol>
